Assertion (A): In alumino thermite process, the metals like iron melts due to the heat evolved in the reaction.
Reason (R): The reaction is: `Fe_(2)O_(3)+2Al to Al_(2)O_(3)+2Fe`

Options

A. Both A and R are true and R is the correct explanation of A.
B. Both A and R are true but R is NOT the correct explanation of A
C. A is true but R is false
D. A is false and R is true.

Explanation

To analyze the assertion and reason given in the question, we need to break down the components of the assertion (A) and the reason (R) step by step.

### Step 1: Understanding the Assertion (A)
The assertion states that in the aluminothermite process, metals like iron melt due to the heat evolved in the reaction.

- The aluminothermite process is a thermite reaction that involves aluminum and a metal oxide (in this case, iron oxide).
- The reaction is highly exothermic, meaning it releases a significant amount of heat.

### Step 2: Understanding the Reaction
The reason provided states the chemical reaction involved:
\[ \text{Fe}_2\text{O}_3 + 2\text{Al} \rightarrow \text{Al}_2\text{O}_3 + 2\text{Fe} \]

- In this reaction, iron(III) oxide (Fe₂O₃) reacts with aluminum (Al) to produce aluminum oxide (Al₂O₃) and molten iron (Fe).
- The heat generated from this reaction is sufficient to melt the iron produced.

### Step 3: Conclusion
Both the assertion and the reason are correct. The heat evolved during the reaction is indeed what causes the iron to melt.

Thus, we can conclude:
- Assertion (A) is true.
- Reason (R) is true and correctly explains the assertion.

### Final Answer
Both the assertion and the reason are true, and the reason correctly explains the assertion.
